骚灵现象，又名喧闹鬼现象、波尔代热斯现象、离奇神动、神动，是一种超自然现象。举凡一切暴力且具有破坏性的灵异事件，被认为是喧闹鬼（或称骚灵，Poltergeist）所造成。陶比胡波执导的电影《鬼哭神号》就是以此现象为题材拍摄的电影。再者，所谓的「喧闹鬼」在德文里意指「吵闹的灵魂」。

目前物理上的解释如下所列：

In folklore and parapsychology, a poltergeist (German for "pounding ghost") is a type of ghost or other supernatural entity which is responsible for physical disturbances, such as loud noises and objects being moved or destroyed. They are purportedly capable of pinching, biting, hitting, and tripping people. Most accounts of poltergeists describe the movement or levitation of objects such as furniture and cutlery, or noises such as knocking on doors.
